LSR Injection Molding
LSR Injection Molding involves injecting liquid silicone rubber—a two-component material—into a heated mold. Unlike traditional thermoplastic injection molding, LSR is a thermosetting material, meaning it retains its shape and properties once cured, making it perfect for demanding applications.
LSR Injection Mold
An LSR injection mold is a precision-engineered tool designed to shape liquid silicone rubber into intricate, high-performance components. Unlike traditional molds, these molds are built to handle the unique properties of LSR—low viscosity, rapid curing, and exceptional flexibility.

Different Types of LSR Injection Molding
From the perspective of specific technology and processing, LSR injection molding can be further divided into the following types:
★ Standard LSR Injection Molding: A robust and economical process for high volumes of medium to high precision silicone component production with minimal material waste.
★ Two-shot/Multi-shot LSR Molding: A branch of LSR injection molding, refering to the molding of two or more materials in the same injection molding machine and process.
★ LSR Overmolding: Used to produce specialized components consisting of two different substrates. In the process, LSR is molded around the finished molded part, metal or other substrate.
